If you’ve been diagnosed with type 2 diabetes, there’s a good chance that you’re not the first person with diabetes in your family. You’re more likely to develop the condition if a parent or sibling has it.
Several gene mutations have been linked to the development of type 2 diabetes. These gene mutations can interact with the environment and each other to further increase your risk.
Scientists have linked several gene mutations to a higher diabetes risk. Not everyone who carries a mutation will get diabetes. However, many people with diabetes do have one or more of these mutations.
It can be difficult to separate genetic risk from environmental risk. The latter is often influenced by your family members. For example, parents with healthy eating habits are likely to pass them on to the next generation.
On the other hand, genetics plays a big part in determining weight. Sometimes behaviors can’t take all the blame.
To date, numerous mutations have been shown to affect type 2 diabetes risk. The contribution of each gene is generally small. However, each additional mutation you have seems to increase your risk.
In general, mutations in any gene involved in controlling glucose levels can increase your risk of type 2 diabetes. These include genes that control:
- the production of glucose
- the production and regulation of insulin
- how glucose levels are sensed in the body
Genes associated with type 2 diabetes risk include:
Tests are available for some of the gene mutations associated with type 2 diabetes. The increased risk for any given mutation is small, however.
Other factors are far more accurate predictors of whether you’ll develop type 2 diabetes, including:
The interactions between genetics and the environment make it difficult to identify a definite cause of type 2 diabetes. However, that doesn’t mean you can’t reduce your risk through changing your habits.
The Diabetes Prevention Program Outcomes Study (DPPOS), a large, 2012 study of people at high risk for diabetes, suggests that weight loss and increased physical activity can prevent or delay type 2 diabetes.
Blood glucose levels returned to normal levels in some cases. Other reviews of multiple studies have reported similar results.
Here are some things you can start doing today to reduce your risk for type 2 diabetes:
Start an exercise program
Slowly add physical activity into your daily routine. For example, take the stairs instead of the elevator or park further away from building entrances. You can also try going for a walk during lunch.
Once you’re ready, you can start adding light weight training and other cardiovascular activities to your routine. Aim for 30 minutes of exercise each day. If you need ideas for how to get started, check out this list of 14 cardio exercises to get you moving.
Create a healthy meal plan
Come up with a weekly meal plan that includes dishes for every meal. Stock up on all of the groceries you’ll need, and do some of the prep work ahead of time.
You can ease yourself into it, too. Start by planning your lunches for the week. Once you’re comfortable with that, you can plan out additional meals.
Choose healthy snacks
Stock up on healthy snack options so you aren’t tempted to reach for a bag of chips or candy bar. Here are some healthy, easy-to-eat snacks you may want to try:
Knowing your risk for type 2 diabetes can help you make changes to prevent developing the condition.
Tell your doctor about your family history with type 2 diabetes. They can decide if genetic testing is right for you. They can also help you reduce your risk through lifestyle changes.
Your doctor may also want to regularly check your glucose levels. Testing can help them with early detection of blood sugar abnormalities or identification of type 2 diabetes warning signs. Early diagnosis and treatment can have a positive impact on your outlook.
